I'm thinking a tight ring package and decked block so the quench area is ideal and higher static compression would produce more cyl pressure and require less advance on the bottom?
What is the cranking pressure?

Don't have those figures atm, but the same set-up is about to be tested on a fresh F/SA Corvette...that will answer some questions for sure. He will be using a maximum of 44 degrees on his runs.
